The short answer
Semi truck insurance for for-hire carriers usually combines primary liability ($1,000,000 for most brokers), motor truck cargo ($100,000 is common), physical damage on the tractor and trailer, and often general liability and trailer interchange. Your price depends on your record, authority age, freight, radius and equipment.
Who this page is for
Owner-operators and small fleets running Class 8 tractors with dry van, reefer, flatbed, tanker or other trailers, under their own authority or leased on. Semi trucks are the most common rig on the road, so there are more insurers in this market than for many specialty trucks, but long-haul miles, high values and heavy weights still make it one of the more carefully underwritten classes.
